T all w/zomz't mag; comem:

Be it known that I, HARRY M. STEPHEN- son, a citizen 0f the UnitedStates, residing at the city and county of Denver and Stute of Colorado,have invented certain new and useful Improvements in Automatic Tape orFilm Reversing Reels, and du declare the following to be a full, clear,and exact de scription of the invention, such a.s Will en able othersskilled in the art to which it apg:rtains to make and use the same,reference ing had to the ac companying drawings, and to the charactersof reference mark'ed thereon, which form a part of this specification.

This invention relates to devices f01" winding film after use, and isespecially designed in the present showin for winding motion picturefilms as they %eave the projecting machine; but it maf be used also forwinding tapes or the ike 0n player 'pianos or similar instruments.

The object of the invention is to so wind the film after use, that itmay be immedi ately returned for reusewithout rewinding to present thebeginning of the film ab the outer part of the real. This applicat1onconstitutes an improvementover that filed by me August 28th, 1919,Serial N0. 320,- 380.

Briefly, the invention mmprises a stati onary cas1ng having therein arotary carner, on which is mounteda reel for internal winding of thefilm, the carrier having movable devices tongage the film as it is woundand adapted to be lifted as they pass the incoming portion of the film.The casing has a cover carrying a film guide and means t0 besition thefilm as it is wound onto the reel. The particular improvements in thisapplication lie in the device f0r the incoming film, the s ecificoperating means for the devices whicl'l engage and hold the film afterbeing wound, und the means f0r determining the pressure of said engagingdevices upon the film. The positioning means comprises a plurality ofsmall rollers on stationary axes, said rollers being so tapered 'and sopositioned as to give the proper dixection to the film which comesvertically to the reel and is then diverted at an angle as it asses int0the reel. The devices for engagmg and holding the posipositioning.tioned film constitute pivoted arms provided with meshing bevel gears.The means for determini-ng the pressureof said engaging devicescomprises a ring carried upon rollers at the periphery 01 the carrierand frictional means secured in the casing wall and bearing a ainst saidrin Thering has connectidn y means of ca les wit'h the film-engagingdevices. As the carrier rotates, the tendency of the ringis t rotate.with it, but engagement Qf the friction devices on the ring retards itsmotion somewhat and transmits a pu*ll upon each of the film-engagingdevices throughihe respective cable.

Thc casing comprises a back 20 and a rim 21, the back having an integralexternal bea1ing 22 to receive the drive shaft 23, which carries apulley 24 having ratchec teeth 25 engaged by a dog 26, secu'red upon thebearing 22. A hub 27 0n the carrier 28 fixedly receives the drive shaft23. The hub 27 bears upon an internal boss 122 upon the casing back 20.The carrier 28 is provided With an annular shoulder 29, forrning .1circular pocket, and asecond annular shoulder 30, forming a.- largercircular pocket. The smaller pocket receives the real back 31, Which hasan integral hub 32, pro vided with a bayonet slot 33, for purposeshereinafter described.

he larger pocket formed by the shoulder 30 receivs the flange 34 of tl1ereel rim 35. The reel back 31 is held against rotation by .means of pins36 in the carrier 28, which project through apertures in the real back,and the real rim is held in its pocket against rotation by means of pins37 (0:4 which three are shown), apertures formed in the flan e 34. Theflange 34 overlaps the reel bac 31 slightly when in operative Position,thereby retaining the back 31 in position While a. 111g 38 011 thebottom 0f' the carrier, and a latch 39 on the top of the carrier,controlled by a spring 40 (Fig. 12),.retain the rim 35 in is poclzet.II. m 35 is composed of two 41 and adapted to be fastene. 41 by means cfa spring Clip 42 on one half of -'the rim which engages a pin 43 011 theotl1er half of the r'nn.

In order 130 properly retain the filrn, as euch convolution, builds upwith the reel 35, fingers 72, mounted on the carrier, are provided,these fingers projecting through slots 71 in the carrier and throughslots in he 1eel back, tne projecting end 015 each finger beingprovicled With a pad for engagement with the film. Each finger isslidably mounted upon a slotted plate 73, secured to the back-of thecarrier, by means 0% a bl0ck 74, in which the respective finger 7 2 ispivote. The finger pivot 75 carries a bevel gear 76, which meshes with asecond bevel gear 77 011 a spindle mounted in brackecs '78, also on theblock 74. The splndle carries a. laterally projecting arm 79, equippedit's outer end With a roller, 80, acleo d to engage a cam roller 81 inthe lower part of the casing, whereby, through he medium of the bevelgears 76 und 77, each fingen 72 is lifted from engagement with the filmas it passes the incorning portion of the film, and the positioningrollers 58. This operation is indicated in the lower .part of Fig. l.

In order to restore each finger 72 to filmafter passing the incoming 1mortion, a spring 82 (Fig. 11) is provicled, this spring being connectedwith one of che brackets 78 and with the spindle 025 ihe bevel gear 7 7.

Each block 74 has connected thereto a eable 83, which asses over apulley 84, mouned acljacent ehe periphery of the cmrier 23, and thence130 a. pin 85, mountecl in an annular friction ring 86, carriecl v.p0n1ollers 87, secured also to the carri 28, adjacent its periphery undpreferaby upon the sznne piv0t pin as the pulley 84.

A.s the carrier rotates, of the ring 86 is to rotate with nur.fr1ction of the pads 90 upon t he ring 86 prodnces a clrs.g there on andresults in a p-arjnl r a:se 1n0tion of the ring 86 up0n 'Ehis lmparts apull to euch ransmitted to the blocks =10 he filmen mging fingers to ullthe Fingers 72 011iperiphery of the carrler anal prouce s 'eni: contactof the fingers wih the film whin the reel 35.

1 2 shonld be noted that in order 10 properly position an l xnaintainthe pressure of fingers 72 upon the enslon of be Springs prcrace by thefriction means 82 ex'ceeds the pull 90 upon the film, the combineclannular friction ring 86. In this manner, proper pressure f the finger72 upon the film is obtained without unduly drawing the block 74 towardthe periphery cf the carrier. By this construction tl1e fingers 72 andtheir blocks 74 are Permitted t0 move inwardly as tl1e film builds upwithin the reel 35.

When tl1e film has been Wound Within the reel 35, the door 50 is opened,carrying with it tl1e slide 51, positioningrollers 58, and the filmguide 59. The auxiliary reel portions of Figs. 17 and 18 are theninserted to assume the osition with relation to the reel back 31, asshown in Fig. 18, the film, howcver, being omitted in Fig.

This auxiliary struct ure comprises a plate 100 cf tl1e sa1ne size 'asthe reel back 31, this plate 100 being provided With r'adially disposedslots 101. A second plate 102, pro vided with curvedslots 103, issuperposed 011 the plate. 100, and the stems "of pins 104 p rojectthrough tl1e slots 101, 103, the pins 104 being secured by means 0fheads 105. A sleeve 106 is axially diSposed in the pla.tes 100, 102, andis pressed outwardly by means of springs 107. The inner end of thesleeve 106 is provided Wit-h an inwardly projecting pin 108, this pinbeing adapted to engage and seat within the bayonet slot 33 of the hub32 011 the reel back 31. T0 remove the film, tl1e pins 104 arepositioned within the film and between the fingers 72. The plate 102 isthen turned t0 move the pins 104 0ut wardly in the slots 101, 103, untilthey engage firmly with the film. Tl1e sleeve. 106 is then pressedinwardly t o cause the pin 108 to enter the bayonet slot 33 and seatinthe inner end thereof, wherebythe parts are retained in osition underthe tension cf the springs The latch 39 at the top of the carrier isthen released, and the top of the reel tipped forfvard until the reelback 31 and flange 34 are withdrawn from their pockets; tl1e reel thenbeing lifted from behind the lug 38 at tl1e bottom of the carrier.

The latch 42 is then opened and the parts 0f the rim are theri swung onthe pivot 41 to remove them frorn the reel thus formed by the reel back31 and the plate 100.

The sleeve 106 is provided with a bearing 109, with a diameter equal t0that of the hub 32 on the reel back 31. These parts 32 und 109 thenconstitute a positive bearing for a spindle by means of which the reelmay be mounted in a motion picture projecting machine.

In order to prepare the carrier 28 to Wind nnother film, another reelback 31 is laced in position, the rim 35 reassemble and placed inposition, the door is closed, tl1e film is passed down through the guide59, and secured in any suitable manner to the rim 35 through door, asshown in Fig. 16.
